Use t
his key when you want to arm your system with one or more zones intentionally
unprotected.
Vent Zones: Your system may have certain windows set as "vent" zones, which are
automatically bypassed if left open when arming the system (you do not need to
manually bypass them). However, if a vent zone window is closed after arming, it
becomes protected and will cause an alarm if opened again while the system is armed.
When bypassing zones:
• The system must be disarmed before you can bypass zones.
• Bypassed zones are unprotected and will not cause an alarm if violated.
•
The system will not allow fire zones to be bypassed.
• Zones are automatically unbypassed when the system is disarmed.

bypassed (e.g., 06, 10, 13, etc.). Single digit zone

When finished, the keypad will momentarily display
a "Bypass" message for each bypassed zone number.

Arm the system as usual. When armed, the arming
message is displayed with "ZONE BYPASSED."
